I had my 950 xl yesterday and I previously owned a 930 so I quickly compared the two and I expected the xl to be superior in every department but I was disappointed by the audio quality. 930 had a deeper richer sound with headset and without it as well. The xl doesn't even support the dolby audio levelling and sound enhancement features even though the processor supports it. The result is a cheap feel. Is there any chance to improve it either by software or firmware updates or it was done purposefully by MS?
